Tournay Abbey () is an active Benedictine monastery in Tournay, Hautes-Pyrénées, France.
A priory was first established on the site in the 11th century, which became an abbey in the 17th century. It was suppressed during the French Revolution.
A new abbey was founded in the 1930s in Madiran and was transferred to Tournay in 1952, the year after construction of a new monastery. The building was completed in 1958.
The abbey remains active and houses a community of approximately 20 monks.
